Synthetic non-Abelian gauge fields and gravitomagnetic effects in tilted Dirac cone systems
Tohid Farajollahpour, S. A. Jafari
In planar tilted Dirac cone systems, the tilt parameter can be made space-dependent by either a perpendicular displacement field, or by chemical substitution in certain systems. We…
Sound of Fermi arcs
Fatemeh Adivehvand, Zahra Faraei, Tohid Farajollahpour +1
Using Green's function of semi-infinite Weyl semimetals we find that the collective charge excitations of Fermi arcs in undoped Weyl semi-metals are linearly dispersing gapless pla…
Optical conductivity of triple point fermions
Alireza Habibi, Tohid Farajollahpour, S. A. Jafari
As a low-energy effective theory on non-symmorphic lattices, we consider a generic triple point fermion Hamiltonian which is parameterized by an angular parameter . We find stro…
The borophene sheet: A solid-state platform for space-time engineering
Tohid Farajollahpour, Zahra Faraei, S. A. Jafari
We construct the most generic Hamiltonian of the structure of borophene sheet in presence of spin-orbit, as well as background electric and magnetic fields. In addition to…
Greens function of semi-infinite Weyl semimetals
Zahra Faraei, Tohid Farajollahpour, S. A. Jafari
We classify all possible boundary conditions (BCs) for a Weyl material into two classes: (i) BC that mixes the spin projection but does not change the chirality attribute, and (ii)…
Topological phase transiton of anisotropic XY model with Dzyaloshinskii-Moriya interaction
T. Farajollahpour, S. A. Jafari
Within the real space renormalization group we obtain the phase portrait of the anisotropic quantum XY model on square lattice in presence of Dzyaloshinskii-Moriya (DM) interaction…
